Does any one know which car companies in Broome will allow you to take a 4WD on the GRR. Many advertise them but searching the fine print doesn't always come up with their restrictions. We intend doing it in June as far as Drysdale then on to Emma Gorge Kununarra Bungle Bungles and back to Broome with a side trip to Cape Leveque. From what I can see the following do not allow you to take their 4WD on the GRR : Europcar, Redspot, Avis, Budget. So who else apart from Hertz Thrify and Britz do?
